    Calling Button_click event in dynamically loaded UserControl from the Main Page

    Hi guys! This is my first post here
    I have this really nagging problem which is driving me crazy for 3 days already.Thought I would come here and post the question in case someone can help!

    I have a created a WebUserControl called AddEditPanel. In the usercontrol I have several text fields and one update button, which, when called is supposed to update some record in the database .

    And then I call that usercontrol dynamically from the mother page. The control loads just fine. ONLY PROBLEM IS THAT I CAN NOT FIND ANY WAY TO CATCH THE BUTTON-CLICK EVENT IN THE MOTHER PAGE. NO MATTER WAHT I DO, THE PAGE JUST DOES A POST BACK AND THATS ALL.

    I have searched the net and this forum and other forums as well. But none of them quite addresses the problem that I am facing.

    Pleasee help me out.
    Thanks to all in advance

      Welcome to the scripts developer network. What version of ASP are you using? What else can you tell us about your system set up that might be applicable (what is your development platform etc?)

          <asp:Button ID="Button1" runat="server" OnClick="Button 1_Click" Text="Button" />

          ascx.cx file:

          using System;
          using System.Data;
          using System.Configur ation;
          using System.Collecti ons;
          using System.Web;

          {


          private void Page_Load(objec t sender, System.EventArg s e)
          {

          {
          Response.Write( "WebUserControl 1 :: Begin Button1_Click <BR>");
          // OnBubbleClick(e );
          Response.Write( "WebUserControl 1 :: End Button1_Click <BR>");
          }

              Does anyone know why I would get this error with the code from previous post?

              'System.Web.UI. Control' does not contain a definition for 'BubbleClick'

              I am dynamically loading my user control in the OnPreInit event, as suggested somewhere else.
